Golden State Killer Map Shows Where Serial Killer Attacked

California authorities have arrested Joseph James DeAngelo as the suspected serial killer in the Golden State Killer case. DeAngelo was a police officer in the 1970s and had been living in Sacramento County for over 30 years, The Sacramento Bee reported.

DeAngelo, 72, was arrested in California on Wednesday morning on two counts of murder for the March 1980 murders of Lyman and Charlene Smith, Ventura County District Attorney Gregory Totten confirmed during a press conference on Wednesday.

"Today, at least we brought the first step towards closure to the victims for these horrendous crimes," said Sheriff Scott Jones of Sacramento County Police Department during a press conference on Wednesday.

The Golden State Killer was a suspected serial killer, rapist and burglar who terrorized California in the 1970s and 1980s. The suspect, who is also known as the East Bay Rapist, is believed to have raped at least 40 victims in Northern California in the 1970s and into the '80s and disappeared. According to the FBI, the killer is also responsible for at least 12 murders.

Authorities were able to determine the suspected rapist was the same person who went on a killing spree in 1979 in Southern California in the early 2000s, according to the San Francisco Chronicle.

The number of incidents are currently listed on the website Cold Case EARONS, which provides extensive information on the East Area Rapist and Original Night Stalker cases. The map below from Cold Case EARONS shows where the Golden State Killer committed his attacks.

The website lists a total of 49 cases, with some of the cases marked by an asterisk from the homicides that have been attributed to the assailant known as the Original Night Stalker. The case went cold after the last suspected murder took place in 1986 in the Orange County city of Irvine.
